Well, the problem is X.com that has the parked domains was sold to someone else so the original owner will not be the same but the domain name will remain the same.

The dilemma was the parked domains and the email and things associated with it. Although the mails can be changed to the appropriate location once they are setup again, this is still something he was asking to avoid.

I had this situation once before, but it is indeed a while ago, by changing the domain name for current account, the domains stay parked for as far as i remember, you can then create a new hosting package for domain x.com.
